yes it is its on and off, days worse than others , but thats the answer ,you have to ride the wave and get off when its over, i learn that, its not going to kill me and that it will end soon. i go on with my life and if bad i force myself to get out house go to mall walk around before i know it , its gone, if i had chest pains i would go outside cut grass see if it was really anxiety or heart attack, lucky justs anxiety. you have to work throught it , dont give up ,you will WIN.
